Private insurers offer a variety of supplemental coverages in both the group and individual markets. These are not designed to provide the primary source of medical or disability protection for an individual, but can assist with unexpected expenses and provide additional peace of mind for insureds. Supplemental coverages include Medicare supplement insurance, hospital indemnity insurance, dental insurance, vision insurance, accidental death and dismemberment insurance and specified disease insurance.
The Children's Health Insurance Program (CHIP) is a joint state/federal program to provide health insurance to children in families who earn too much money to qualify for Medicaid, yet cannot afford to buy private insurance. The statutory authority for CHIP is under title XXI of the Social Security Act. CHIP programs are run by the individual states according to requirements set by the federal Centers for Medicare and Medicaid Services, and may be structured as independent programs separate from Medicaid (separate child health programs), as expansions of their Medicaid programs (CHIP Medicaid expansion programs), or combine these approaches (CHIP combination programs). States receive enhanced federal funds for their CHIP programs at a rate above the regular Medicaid match.
An alternative proposal is to subsidize private, non-profit health insurance cooperatives to get them to become large and established enough to possibly provide cost savings Democratic politicians such as Howard Dean were critical of abandoning a public option in favor of co-ops, raising questions about the ability of the cooperatives to compete with existing private insurers. Paul Krugman also questioned the ability of cooperatives to compete.
Before the development of medical expense insurance, patients were expected to pay health care costs out of their own pockets, under what is known as the fee-for-service business model. During the middle-to-late 20th century, traditional disability insurance evolved into modern health insurance programs. One major obstacle to this development was that early forms of comprehensive health insurance were enjoined by courts for violating the traditional ban on corporate practice of the professions by for-profit corporations. State legislatures had to intervene and expressly legalize health insurance as an exception to that traditional rule. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, and emergency health care procedures, and most prescription drugs (but this is not always the case).
Costs for employer-paid health insurance are rising rapidly: between 2001 and 2007, premiums for family coverage have increased 78%, while wages have risen 19% and inflation has risen 17%, according to a 2007 study by the Kaiser Family Foundation. Employer costs have risen noticeably per hour worked, and vary significantly. In particular, average employer costs for health benefits vary by firm size and occupation. The cost per hour of health benefits is generally higher for workers in higher-wage occupations, but represent a smaller percentage of payroll. The percentage of total compensation devoted to health benefits has been rising since the 1960s. Average premiums, including both the employer and employee portions, were $4,704 for single coverage and $12,680 for family coverage in 2008.
